Which set of statements below is entirely true?

Which set of statements below is entirely true?

• A. Pneumatic guns use air to fire pellets and BBs; Never shoot directly at the water surface; Each firing point should have a minimum of four feet; In the event of a tie score, the first tiebreaker used is the greatest number of center shots.
• B. Pneumatic guns use air to fire pellets and BBs; Never shoot directly at the water surface; Each firing point should have a minimum of two feet; The match may be rescheduled or cancelled if not completed.
• C. A CO2 gun uses liquid gas stored in a bottle; It is safe to shoot if the barrel is clogged; The total weight of an unloaded BB gun may not exceed 7 pounds; The first tiebreaker is the total misses.
• D. All of the above.

Answer: (A)

The question tests practical rules about how air-gun matches are run, including what powers the guns, safe range setup, and how ties are decided. The statements that are entirely true describe: pneumatic guns operating on compressed air to launch pellets or BBs; a safety rule that you should never shoot directly at the water surface; a requirement that each firing point has a substantial width (four feet) to ensure safe spacing; and a tie-break rule that the first tiebreaker is the greatest number of center hits, which rewards precision. Why this set fits all those points: pneumatic systems use compressed air to propel projectiles, which is distinct from CO2 systems; aiming at water is commonly prohibited because water surfaces can cause unpredictable rebounds and range safety concerns; a four-foot minimum for firing points helps maintain safe lanes and prevent interference between shooters; and using the number of center shots as the first tiebreaker is a standard way to resolve ties by favoring accuracy on the target center. The other sets mix in inaccuracies—for example, describing CO2 guns as using “liquid gas” stored in a bottle isn’t how CO2 power is typically characterized, and saying it’s safe to shoot if the barrel is clogged is unsafe and incorrect; and a different tiebreaker (such as total misses) or a smaller minimum firing-point distance would not align with the established rules. Therefore, only the first option is entirely true.
